Daniel Craig Reveals His Favorite Bond Girl

Quantum of Solace star Daniel Craig only has eyes for one Bond girl – his own.

At the world premiere of the new James Bond film, Craig strolled the red carpet Wednesday night in London with girlfriend, Satsuki Mitchell, who wore a Ralph Lauren Collection gown and eagerly told reporters that his favorite Bond girl was "the one on my arm."

"He was a bit spotlight shy and glued to his girlfriend," a source tells PEOPLE. "She straightened his tie a lot and whispered what seemed words of encouragement."

Inside the Odeon theater, when Craig was called to the stage along with the cast, he showered attention on Mitchell – an American movie producer – helping her up the steps and making sure she knew where to stand.

"He was the only actor to say a few words and he told his girlfriend he loved her," the source says, adding that Craig "seemed really confident and comfortable speaking from the stage."

The happy couple skipped out on the film’s splashy afterparty, where guests included current Bond girls Olga Kurylenko (who sat in a booth chatting with friends) and Gemma Arterton (in an eye-catching hot pants-and-dress ensemble), former Bond Girl Grace Jones, and Jack White, who sings the film's theme song with Alicia Keys.
